STM32 Cube library - CMSIS and HAL for F0, F4, F7, H7, L0, L4 and WB microcontrollers

This repository contains a copy of STMicroelectronic's STM32 Cube firmware library, with CMSIS-device and HAL code for STM32F0xx, STM32F4xx, STM32F7xx, STM32H7xx, STM32L0xx, STM32L4xx and STM32WBxx microcontrollers. Minor changes are applied to the HAL source to support MicroPython's port to the STM32.

The "vendor" branch contains the original sources and is updated from time-to-time when new versions become available. The upstream sources are provided as separate releases (and in separate archives) for each microcontroller class (eg F4, F7, L4). These are merged together here in the "vendor" branch, because the idea of the HAL code is that it provides a uniform interface to all microcontroller classes. The commits in the "vendor" branch are tagged as appropriate with a tag that describes all the available versions at that commit, for example F4-1.5.0+F7-1.1.0+L4-1.3.0.

There are then working branches that branch at a given vendor tag and apply minor patches to the vendor code, for example work-F4-1.5.0+F7-1.1.0+L4-1.3.0. The patches/commits that form a given working branch are reapplied (with conflict resolution) to newer vendor tags to create the next working branch.

Original sources

The sources are obtained from http://st.com

For all .c and .h files the following processing has been done to the original files before committing them here:

  • lines endings changed to unix style
  • trailing spaces removed
  • tabs expanded to 4 spaces
  • non-ASCII chars converted to their ASCII equivalent

A shell function to do this processing is:

function clean_code() {
    chmod 644 $1
    cat $1 | awk "{sub(/[\t ]*\r/,\"\")}1" | expand -t 4 | tr \\200\\205\\211\\221\\222\\223\\224\\226\\231\\244\\261\\265\\302\\327\\342 \'??\'\'\"\"\\-\'??u?x\' > tmp$$
    mv tmp$$ $1
}
find path -type f | while read file; do echo "$file"; clean_code "$file"; done

Directories from the original sources are mapped into this repository according to the following:

Drivers/STM32F4xx_HAL_Driver/Inc ->          STM32F4xx_HAL_Driver/Inc
Drivers/STM32F4xx_HAL_Driver/Src ->          STM32F4xx_HAL_Driver/Src
Drivers/CMSIS/Device/ST/STM32F4xx/Include -> CMSIS/STM32F4xx/Include
Drivers/CMSIS/Device/ST/STM32F4xx/Source  -> CMSIS/STM32F4xx/Source

And similar for the other microcontroller classes.

You can’t perform that action at this time.
